Description

本発明は、かかる事情に鑑みてなされたものであり、その目的は、決算関連情報からの要因抽出を効率的かつ柔軟に行い、投資家や機関投資家にとって有用な情報を提供することである。 The present invention has been made in view of such circumstances, and its object is had efficiently and flexibly row factors extracted from financial-related information, to provide information useful to investors and institutional investors is there.

かかる課題を解決すべく、第１の発明は、パターン記憶部と、文書解析部と、レポート作成部とを有し、決算関連情報を分析する決算分析システムを提供する。パターン記憶部には、要因パターンが記憶されている。この要因パターンは、少なくとも科目および金額情報を含む会計上の事象の表現と、この事象の要因の表現とを有する。文書解析部は、処理対象となる文の形態素列と、パターン記憶部に記憶された要因パターンとを比較する。処理対象となる文の形態素列は、この形態素列を構成する形態素またはその組み合わせに対して、少なくとも科目および金額を分類する属性毎に固有の属性ラベルを付与することによって抽象化されている。また、文書解析部は、要因パターンと一致した形態素列について、この要因パターンによって指定された部分を要因として抽出し、抽出された要因を形態素列における科目および金額情報と紐付けて、１組のデータとして記憶する。レポート作成部は、１組のデータに基づいて、決算分析レポートを出力する。 In order to solve such a problem, a first invention provides a settlement analysis system that includes a pattern storage unit, a document analysis unit, and a report creation unit and analyzes settlement-related information. The pattern storage unit stores a factor pattern. The factor pattern has an expression of an accounting event including at least the item and amount information, and an expression of a factor of the event. The document analysis unit compares the morpheme sequence of the sentence to be processed with the factor pattern stored in the pattern storage unit. The morpheme sequence of the sentence to be processed is abstracted by assigning a unique attribute label to each morpheme constituting the morpheme sequence or a combination thereof, at least for each attribute for classifying the subject and the amount of money. In addition, the document analysis unit extracts a part specified by the factor pattern as a factor from the morpheme string that matches the factor pattern, associates the extracted factor with the item and amount information in the morpheme string, and creates a set of Store as data. The report creation unit outputs a settlement analysis report based on one set of data.

また、第２の発明は、少なくとも科目および金額情報を含む会計上の事象の表現と、この事象の要因の表現とを有する要因パターンが予め記憶されているコンピュータを用いて、決算関連情報を分析する決算分析プログラムを提供する。このプログラムは、以下の第１から第３のステップを有する処理をコンピュータに実行させる。第１のステップでは、処理対象となる文の形態素列と、パターン記憶部に記憶された要因パターンとを比較する。処理対象となる文の形態素列は、この形態素列を構成する形態素またはその組み合わせに対して、少なくとも科目および金額を分類する属性毎に固有の属性ラベルを付与することによって抽象化されている。第２のステップでは、要因パターンと一致した形態素列について、この要因パターンによって指定された部分を要因として抽出し、抽出された要因を形態素列における科目および金額情報と紐付けて、１組のデータとして記憶する。第３のステップでは、１組のデータに基づいて、決算分析レポートを出力する。 Further, the second invention analyzes settlement-related information using a computer in which a factor pattern having at least an accounting event expression including at least item and amount information and an event factor expression is stored in advance. To provide a financial analysis program. This program causes a computer to execute processing having the following first to third steps. In the first step, the morpheme sequence of the sentence to be processed is compared with the factor pattern stored in the pattern storage unit. The morpheme sequence of the sentence to be processed is abstracted by assigning a unique attribute label to each morpheme constituting the morpheme sequence or a combination thereof, at least for each attribute for classifying the subject and the amount of money. In the second step, for a morpheme sequence that matches the factor pattern, a part specified by the factor pattern is extracted as a factor, and the extracted factor is associated with the item and amount information in the morpheme sequence to form a set of data. To be stored. In the third step, a settlement analysis report is output based on one set of data.

本発明によれば、文そのものではなく、文を形態素解析した上で属性ラベルによって抽象化された形態素列が、予め定義された要因パターンと比較される。そして、両者が一致した場合、この形態素列のうち、要因パターンによって指定された部分が要因として抽出される。要因パターンとの比較を属性ラベルによって抽象化された形態素列ベースで行うことで、定義すべき要因パターンの数を有効に抑制でき、要因抽出を効率的かつ柔軟に行うことが可能となる。それとともに、科目、金額情報および要因を紐付けて１組のデータとして記憶し、これに基づいて決算分析レポートを出力することで、資家や機関投資家にとって有用な情報を提供できる。 According to the present invention, not a sentence itself, but a morphological analysis of a sentence, and a morphological sequence abstracted by an attribute label are compared with a predefined factor pattern. Then, when the two match, the part specified by the factor pattern in the morpheme sequence is extracted as the factor. By performing the comparison with the factor pattern based on the morpheme sequence abstracted by the attribute label, the number of factor patterns to be defined can be effectively suppressed, and the factor extraction can be performed efficiently and flexibly. At the same time, the subject, the amount information, and the factor are linked and stored as a set of data, and a financial analysis report is output based thereon, thereby providing useful information for investors and institutional investors.
